Overview
The CD4504BE-G, produced by Texas Instruments, is a CMOS Hex Voltage Level Shifter integrated circuit. This device consists of six circuits designed to shift input signals from one logic level to another, specifically from the VCC logic level to the VDD logic level. It is particularly useful for translating TTL signals to CMOS logic levels or between different CMOS levels. The CD4504BE-G is part of the CD4000 family and is available in various package types, including 16-lead dual-in-line plastic packages (DIP), small-outline packages (SOIC), and thin shrink small-outline packages (TSSOP).
